Proceedings of the 2020 Computational Techniques and Applications Conference

Abstract

CTAC-2020

Sydney, Australia

30 August -- 2 September 2020

The 20th biennial Computational Techniques and Applications Conference was originally planned to take place at the University of New South Wales from 30 August until 2 September, 2020. As the Covid-19 pandemic worsened, it became clear that travel restrictions and other measures meant that the conference could not be held in its usual form, and the organising committee decided to move the conference online.

The ANZIAM Special Interest Group in Computational Mathematics is responsible for this series of conferences, the first of which was held in 1981. Participants of the conference are able to submit a short article based on their presentation for publication in this special section of the ANZIAM Journal (Electronic Supplement). The editors, William McLean and Shev MacNamara, thank the referees whose efforts have helped improve the quality of these conference proceedings.

This Special Section of the ANZIAM Journal (Electronic Supplement) contains the refereed conference papers.

The eight keynote presentations were as follows.

• Konstantin Brenner, University of Nice Sophia-Antipolis
  Numerical modeling of two-phase flow in fractured porous media
• Michael Feischl, TU Vienna
  Numerical analysis and machine learning.
• David Harvey, UNSW
  Fast Fourier transforms of prime length.
• Trevor McDougall, UNSW
  Some mathematical aspects of physical oceanography.
• Kate Smith-Miles, University of Melbourne
  In search of algorithmic trust \dots show us the stress-testing!
• Catherine Powell, University of Manchester
  Adaptive and multilevel stochastic Galerkin methods for PDEs with uncertain inputs.
• Aretha Teckentrup, University of Edinburgh
  Convergence of Gaussian process emulators with estimated hyper-parameters.
• Alex Townsend, Cornell University
  The ultraspherical spectral method.

The presentation by Trevor McDougall was a public lecture. The conference attracted 131 registered participants, and featured a total of 81 contributed talks.
